Variation in life-history traits and their plasticities to elevational transplantation among seed families suggests potential for adaptative evolution of 15 tropical plant species to climate change

• Premise of the study: Because not all plant species will be able to move in response to global warming, adaptive evolution matters largely for plant persistence. As prerequisites for adaptive evolution, genetic variation in and selection on phenotypic traits are needed, but these aspects have not been studied in tropical species. We studied how plants respond to transplantation to different elevations on Mt. Kilimanjaro, Tanzania, and whether there is quantitative genetic (among-seed family) variation in and selection on life-history traits and their phenotypic plasticity to the different environments. • Methods: We reciprocally transplanted seed families of 15 common tropical, herbaceous species of the montane and savanna vegetation zone at Mt. Kilimanjaro to a watered experimental garden in the montane (1450 m) and in the savanna (880 m) zone at the mountain’s slope and measured performance, reproductive, and phenological traits. • Results: Plants generally performed worse in the savanna garden, indicating that the savanna climate was more stressful and thus that plants may suffer from future climate warming. We found significant quantitative genetic variation in all measured performance and reproductive traits in both gardens and for several measures of phenotypic plasticity in response to elevational transplantation. Moreover, we found positive selection on traits at low and intermediate trait values levelling to neutral or negative selection at high values. • Conclusions: We conclude that common plants at Mt. Kilimanjaro express quantitative genetic variation in fitness-relevant traits and in their plasticities, suggesting potential to adapt evolutionarily to future climate warming and increased temperature variability.

Public service use by residents of Jackson Hinds Gardens before and after enrollment

Homelessness is associated with high use of public services such as health care and criminal justice services. Intervention designs to reverse homelessness have broadly fallen into two categories: either standard care which employs requisitely addressing the causes of homelessness, or housing first, which emphasizes provision of permanent housing without requisitely addressing the causes of homelessness. Multiple cities have recently commenced housing first interventions. Locally, Houston’s first housing first development is the Jackson Hinds Gardens project. The purpose of this study is to analyze the public service use of residents of housing first in Houston. Residents of Jackson Hinds Gardens who have been enrolled for at least 6 months were evaluated for public service use for an equal amount of time preceding and during their residence at Jackson Hinds. Resident interactions with county health services and criminal justice entities were determined by electronic database searches; these data were supplemented by life experience interview data. Service usage values pre- and post-enrollment at Jackson Hinds Gardens were compared by paired t-test analyses. We found that ER and inpatient usage decreased following enrollment in Jackson Hinds, although these reductions were not significant. In contrast, outpatient care and number of medications significantly increased following enrollment. These analyses inform on the effects of housing first in another major city, as well as informing the ethical considerations regarding housing first versus standard care. ^

Illustrated Botanical Books, Fifteenth, Sixteenth, Seventeenth Centuries

No attempt has been made for a comprehensive coverage of the many outstanding illustrated botanical books for this three hundred year period. Rather the aim has been for a combination of interesting illustrators and famous botanists. Like the exhibit on fine bird books, these books on display have been taken from the Rare Books division of Special Collections.

Pollen assemblages of modern soil samples from the Old Botanical Garden of the University of Göttingen

The importance of pollen analytical data for the reconstruction of the natural conditions and their changes caused by human impact in prehistorical and historical times is beyond all doubt. Pollen analysis can, however, be hampered by poor pollen preservation and low pollen concentrations. As an example pollen assemblages from excavation areas near Pompeii (see doi:10.1594/PANGAEA.777531) and from the Old Botanical Garden of the University of Göttingen are discussed. A pollen diagram (see doi:10.1594/PANGAEA.820590) from the site Höllerer See in Austria (N of the city of Salzburg) demonstrates the intensive agricultural influence on the vegetation of the area during Roman and Medieval times. Human influence was much weaker during the Iron and the Bronze ages. There is no indication of human impact on the vegetation during the Migration period.

Bioaccessibility of heavy metals and risk assessment in urban gardens of Madrid

Human health problems and solutions. Urban gardening has spread worldwide in recent years as it enhances food security and selfsupply and promotes community integration. However urban soils are significantly enriched in trace elements relative to background levels. Exposure to the soil in urban gardens may therefore result in adverse health effects depending on the degree of contact during gardening, infant recreational activities and ingestion of vegetables grown in them. In order to evaluate this potential risk, 36 composite samples were collected from the top 20 cm of the soil of 6 urban gardens in Madrid. The aqua regia (pseudototal) and glycine-extractable (bioaccessible) concentrations of Co, Cr, Cu, Ni, Pb and Zn were determined by atomic absorption spectrophotometry. Additionally, pH, texture, Fe, Ca, and Mn concentrations, and organic matter and calcium carbonate contents were determined in all urban gardens and their influence on trace element bioaccessibility was analyzed.

Bioaccessibility of metals and human health risk assessment in community urban gardens

Pseudo-total (i.e. aqua regia extractable) and gastric-bioaccessible (i.e. glycine + HCl extractable) concentrations of Ca, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were determined in a total of 48 samples collected from six community urban gardens of different characteristics in the city of Madrid (Spain). Calcium carbonate appears to be the soil property that determines the bioaccessibility of a majority of those elements, and the lack of influence of organic matter, pH and texture can be explained by their low levels in the samples (organic matter) or their narrow range of variation (pH and texture). A conservative risk assessment with bioaccessible concentrations in two scenarios, i.e. adult urban farmers and children playing in urban gardens, revealed acceptable levels of risk, but with large differences between urban gardens depending on their history of land use and their proximity to busy areas in the city center. Only in a worst-case scenario in which children who use urban gardens as recreational areas also eat the produce grown in them would the risk exceed the limits of acceptability

A taxonomic tool for identifying needle remains of south-western European Pinus species of the Late Quaternary

This work provides a tool whereby the needle remains of native, south-western European Pinus spp. can be easily identified from species-specific epidermal features. To construct this tool, the needles of P. uncinata, P. sylvestris, P. nigra, P. pinaster, P. pinea and P. halepensis were gathered across the Northern Hemisphere range of each taxon and compared with non-indigenous trees growing in two South Australian Botanic Gardens. Three needles from each of these species were taken from three adult trees growing at three different localities. Light microscopy was used to observe the key epidermal and stomatal features of the needles. To improve interpretation, additional scanning electron microscopy samples were prepared. Epidermal features, including variation in the diameter of the epistomatal chamber aperture (pore), are described. A taxonomic key based on the size, shape and arrangement of the subsidiary cells of the stomatal complexes was constructed. This key enables the identification of pine needle fragments at the species level (except those belonging to the group P. gr. nigra-uncinata). Despite their overlapping range, pore size was helpful in distinguishing between P. nigra and P. uncinata and between three groups of species. Isolated stomata were also observed. Cluster and discriminant analyses of stomatal variables described in earlier studies were performed. Overlap in guard cell variables hampers species-level identification of isolated stomata. Species discrimination is improved if groups of ecological affinity are considered.

J.A.D.E. jardín y arquitectura doméstica del este: (la casa contemporánea japonesa, el refugio y el jardín, Tokio: 1991-2011)

El capítulo 1 de esta tesis doctoral describe conceptos relativos a la ontología y a la arquitectura como, por ejemplo, la cuestión de “El lugar” o “Basho” o el espacio visto desde un punto de vista filosófico. En este capítulo se examinan las diferencias y similitudes entre la ideología oriental y la filosofía de occidente a lo largo de la historia y se esbozan los puntos comunes entre ambas en cuestiones que atañen al habitar. En el capítulo 2, estos conceptos se enumeran y ordenan y se extraen diferentes conclusiones en cuanto a la percepción de valores como el espacio o el vacío, fundamentales para entender la arquitectura y el paisaje en las culturas de Oriente y Occidente. El capítulo 3 describe el paisaje oriental y el jardín chino a modo de prólogo del de Japón. Este capítulo introduce al lector en la historia del jardín y explica las transformaciones que éste ha sufrido a lo largo de la historia de China. El capítulo 4 es una asimilación de los conceptos examinados en los capítulos 1,2 y 3 y en él se analizan los aspectos compositivos fundamentales del jardín chino y sus elementos como, por ejemplo, el centro, el límite, el agua o la montaña. El capítulo 5 consiste en una introducción al paisaje japonés que comienza con el estudio de su geografía, su lengua, su literatura y sus períodos históricos más importantes previos a la era moderna: la era primitiva “Jomon”, la era “Yayoi”, los tres Shogunatos y la Revolución Meiji. La segunda parte del capítulo 5 describe los jardines japoneses a lo largo de la historia tales como el jardín Karesansui, los jardines de Kioto o el arte del jardín Tatebana, entre otros. El capítulo 6 comienza con una copia del texto medieval japonés, “HOJOKI”. Al igual que en los capítulos 2 y 4, en el capítulo 6 se extraen los valores del capítulo anterior, esta vez, mediante un comentario de texto. En esencia, este libro demuestra la importancia de la “cabaña en la naturaleza” para la cultura japonesa, así como la relación del espacio doméstico y el jardín a lo largo de su historia. El capítulo 7 describe la evolución del paisaje de la ciudad china en paralelo a la evolución del paisaje urbano japonés que se desarrolla en el capítulo 9. El capítulo 8 es un nexo de unión entre los capítulos 7 y 9 puesto que explica las influencias paisajísticas y urbanas mutuas entre las culturas china y japonesa a lo largo de la historia como es el caso del trazado de las antiguas ciudades capitales chinas y japonesas o el de los paisajes y urbes proyectados sobre la topografía de Manchuria durante la ocupación japonesa de China. El capítulo 9 describe el paisaje japonés moderno, sus ciudades y sus paisajes interurbanos como, por ejemplo, el Tokai-do. A continuación describe la evolución de la arquitectura y el jardín japonés a lo largo del siglo XX, los principales movimientos de vanguardia, las circunstancias económicas que llevaron al país a la crisis de los 90 y la lenta recuperación económica posterior. Por último, este capítulo explica la destrucción del paisaje del norte tras El Gran Terremoto del Este del 2011 y su recuperación a corto plazo. El capítulo 10 se compone de tres entrevistas a tres figuras relevantes del mundo académico y de la arquitectura japonesa. Algunos de los temas que exponen son la arquitectura doméstica japonesa, el jardín y la naturaleza de esta cultura, la situación de la ciudad de Tokio o el rol del arquitecto en la sociedad contemporánea, entre otros. Además de estas cuestiones, se debate acerca de los recursos y la recuperación del país tras El Gran Terremoto del Este de Japón. Finalmente, el capítulo 11 consiste en un estudio en profundidad acerca del paisaje de la ciudad de Tokio y el espacio doméstico y el jardín en base a los conceptos estudiados en los capítulos 1 y 2 y en relación a los valores paisajísticos vistos en los capítulos 3,4,5 y 6, además de los temas urbanos y topográficos estudiados en los capítulos 7,8,9 y 10. En este capítulo se estudia la figura del sujeto individual y colectivo, el refugio, el jardín, las acciones urbanas del Machizukuri, el parque y la morfología y evolución de los barrios centrales de Tokio y sus espacios domésticos y parques y jardines vistos a través de los datos estadísticos proporcionados por el gobierno. Además, el texto estudia un total de 21 casos seleccionados y analizados a través de la comparación de cerca de 800 viviendas domésticas publicadas entre 1991 y 2011 en las revistas de gran prestigio nacional e internacional, Shinkenchiku Jutakutokushu y GA Houses. Tras el análisis de los casos de estudio, se extraen una serie de conclusiones y clasificaciones del jardín en el espacio doméstico del centro de Tokio en dicho periodo. Los últimos tres capítulos de la tesis doctoral se dividen en: una traducción al inglés del resumen y las conclusiones más importantes del capítulo 11 (capítulo 12) una conclusión y resumen homólogos en japonés (capítulo 13) y un cuaderno de dibujos a mano realizado por la autora sobre especies botánicas naturalizadas domésticas de la ciudad de Tokio (capítulo 14) ABSTRACT Chapter 1 of this Ph.D. thesis describes concepts related to ontology and architecture like the issue of “The place” in Japan, or “The space” as seen from a philosophic point of view. In this chapter, the differences between the essential ancient Asian ideology and the philosophical contemporary thought of the East are discussed, and at the same time the transcendental thought coming from the West is analysed and compared to both of them. In Chapter 2 these concepts are analysed specifically in the field of “inhabiting the domestic space” and the text fathoms the common points between Eastern and Western thought relating to the house and the garden. Chapter 3 describes the oriental landscape and garden of China as a prologue to that of Japan. This chapter starts with a brief description of the history of the garden in the East and the West and introduces the reader into the geography and changes that have taken place in China since the birth of its culture. Chapter 4 entails a brief assimilation of what has been deduced from chapters 1, 2 and 3. In this chapter the compositive and design aspects of the Chinese garden are described, aspects such as centre, limit, the element of the mountain, emptiness, water, and vision or the theatre. Chapter 5 is an introduction to the history of landscape and architecture in Japan that starts with a geographical insight into the country and with a short summary about the language, the primitive “Jomon” culture, the “Yayoi” era , the three Shogunates.and the Meiji Revolution. In the second part of chapter 5, the text describes Japanese gardens throughout history, for example the Karesansui garden, the history of Kyoto and its gardens, the garden in relationship with art and with Japanese literature or the art of Tatebana. Chapter 6 starts with a copy of the medieval text “HOJOKI” and discusses issues such as the meaning of “the hut in the nature” for Japanese culture and its relationship with the domestic space and the garden. Chapter 7 discusses the development of cities in the landscape in Chinese culture in parallel with an observation of the evolution of cities in Japanese culture and landscape. Chapter 8 is the crux of the Ph.D. research as it explains the mutual influences of landscape, urban planning, construction and architecture between Japan in China. Chapter 9 describes the Japanese urban planning since the very first urban developments and develops a study on the evolution of the Japanese cities and roads (like the Tokai-do) in the landscape. Also, it describes the reconstruction of the cities of Japan after the Second World War, the cultural vanguard movements, the economical circumstances that led to the Japan´ s economic crisis of the 90´s and the slow recovery of its economy. Also, at the end of this chapter, the text analyses the event of the Great East Japan Earthquake of 211. Chapter 10 of this Ph.D. research is composed of a number of interviews with architects and professors about architecture, nature in the domestic space, the role of the architect nowadays in addition to facts about energy and about the Great East Japan Earthquake . Finally, chapter 11 consists of a deep study concerning the current situation in the city of Tokyo and the relationship between its domestic spaces (dwellings) and gardens based on the philosophical values studied in chapters 1 and 2, aswell as the landscape values of the garden studied in chapters 3,4,5, and 6 plus the information about the cities in the landscape studied in chapters 7,8, 9 and 10. In this chapter the main goal is to study the human being, the refuge, the garden, the urban planning actions of Machizukuri, the park and the morphology and evolution of the central quarters of Tokyo and of its domestic spaces and parks seen through the statistical data provided by the Japanese government in the last decades. Also, the text provides a study on 21 cases selected and analysed through the comparison of around 800 domestic spaces designed in between 1991 and 2011 and published in “Shinkenchiku Jutakutokushu” and “GA Houses” magazines. After these study cases, a number of conclusions are developed and also a classification of the domestic garden in the center of Tokyo. The last three chapters of this Ph.D. work are divided in: the translation to English of the summary and main conclusions of chapter 11 of the research in Chapter 12, the translation to Japanese of the summary and main conclusions of chapter 11 of the research in Chapter 13, and a collection of hand-drawings done by the author about the botanical species found in the gardens of the domestic realms of Tokyo in Chapter 14.

A History of Transplants: A Study of Entryway Gardens at Amache

Previous research shows that during the period of Japanese American internment gardening became a popular activity for the interned. Primarily approached historically, little work has been conducted to archaeologically analyze the efforts of landscaping by former internees. Gardening activity can paint a better picture of Japanese American identity during the period of forced confinement. This research investigates internee gardens methodologically through surface survey, ground penetrating radar, excavation, oral history, soil chemistry, archaeobotany, and palynology. The thorough investigation of landscaping efforts of internees builds upon knowledge of expression within Japanese American relocation centers, as well as the understanding of a lineage of gardening as Japanese immigrant tradition. Using available materials, gardeners adapted both tradition and environment for the purpose of improving conditions under internment and maintaining an affiliation to heritage. My examination of internee landscaping better explains how many collectively maintained, adapted, and publicly expressed an ethnic identity.
